TrainGrid64: 3-Wagon Train Network

Overview

TrainGrid64 is a compact train network that divides the entire base into 64×64 tile cells connected by a standardized 3-wagon train network.

Highlights

1. Each grid is 64×64 tiles (2×2 Factorio chunks), providing perfect alignment with the game's map structure
2. Most factories are compact enough to fit within a single grid cell (except for Cargo Landing Pad which requires a 3×3 grid)

Three Layers

1. Physical Layer

• Standardized grid cells (1x1, 1x2, 2x2) for factory layout
• Rail, stations, signal infrastructure preventing deadlock
• Full logistical coverage with roboports

2. Transport Layer

• Train Standard: 1 locomotive + 3 wagons
• Fuel Stations: Automated refueling infrastructure using a global interupt "Auto Fuel"
• Provider Stations: Supply a single resource type with automatic priority adjustment
• Requester Stations: Seven configurations (111, 112, 123, 11F, 12F, 1FF, and FFF) for different item/fluid combinations. (Each requester station can request up to 3 different items from the network)

3. Factory Layer

• Pre-optimized production blueprints (science, chips, etc.)
• Templates for custom factory design

Limitations

1. No Water: Water is not transported via the train network; blocks with pump must be built on water or use a pump anywhere mod
2. No Defenses: Designed for peaceful play; defense structures not included in the design
3. Efficiency: The compact grid size trades some efficiency compared to larger train grid systems
4. Stability: Factories in the Factory Layer are still under refinement and subject to changes that may contain bugs. The Physical Layer and Transport Layer are very stable. I have used this blueprint book to play multiple times, achieving SPM up to 3000, not encountering problems like deadlock even in dense setups.

Usage Workflow

1. Deploy the physical grid layout
2. Set up provider stations for resources, like coal, iron, copper, stone, oil
3. Build a fuel station using coal. It contains a train that will fetch coal from the provider station to refuel trains in this network. (As this train wants to refuel itself but the fuel station is empty, you need to set the train to skip the auto fuel interrupt for once)
4. Build factories one by one, let the network run
